BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to compositions that include botanical extracts that can be used to reduce the redness associated with acne lesions, improve skin clarity through dermal remodeling, and protect the skin from additional acne breakouts. The compositions of the present invention can also be used to treat or prevent a wide variety of skin conditions. In particular, the present invention concerns topical skin care compositions that include Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, Hydrolyzed soy protein, Navy bean extract, or Mushroom extract, or any combination thereof. In particular aspects, the composition includes a combination of Epilobium angustifolium (Canadian Willowherb) extract, Arctium lappa (Burdock) root extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract.

B. Description of Related Art

Salicylic acid, benzoic acid, benzoyl peroxide, and tretinoin are known anti-acne ingredients. Problems/side effects associated with these ingredients include dry skin, scaly skin, and flaky skin. They can also irritate the skin, which causes the skin to appear red and feel like it is burning. Such irritation adds to the already painful sensation associated with the presence of acne on the skin.

SUMMARY OF THE INVENTION

The present invention overcomes deficiencies in the art by providing anti-acne compositions that can treat, reduce, or prevent the appearance of the signs of acne on skin (e.g., comedones, papules, pustules, nodulocystic lesions, skin redness, etc.). These compositions can include Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, Hydrolyzed soy protein, Navy bean extract, or Mushroom extract, or any combination thereof. In particular aspects, the composition includes a combination of Epilobium angustifolium (Canadian Willowherb) extract, Arctium lappa (Burdock) root extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract. In other aspects, the combination of ingredients can be Ribes nigrum (Black curant) leaf extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, hydrolyzed soy protein, Epilobium angustifolium (Canadian Willowherb) extract, and Arctium lappa (Burdock) root extract. In even a more particular aspect, the combination of ingredients can be Ribes nigrum (Black curant) leaf extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, hydrolyzed soy protein, Epilobium angustifolium (Canadian Willowherb) extract, Arctium lappa (Burdock) root extract, navy bean extract, and mushroom extract.

The compositions can also include an added benefit of reducing or preventing the appearance of dry, scaly, flaky skin and skin irritation. That is, the compositions of the present invention can reduce, prevent, or treat the signs of acne on skin while also reducing or preventing or avoiding side-effects such as dry, scaly, flaky skin and skin irritation. These side-effects can be reduced or prevented or avoided even if anti-acne ingredients that are known to cause such side-effects (e.g., salicylic acid, benzoic acid, benzoyl peroxide, tretinoin, etc.) are incorporated into the compositions of the present invention at effective amounts.

As noted above, the compositions of the present invention can include Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, Soy extract, Navy bean extract, or Mushroom extract, or any one of, any combination of, or all of such ingredients. Further, as shown in the figures and examples (which are incorporated into this section by reference), the inventors have discovered that the combination of Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract produce synergistic and complimentary effects that are beneficial to skin and to treating or preventing acne. The compositions can also include other anti-acne ingredients, even those known to cause undesirable side-effects such as dry, flaky, scaly skin or skin irritation (e.g., salicylic acid, benzoic acid, benzoyl peroxide, tretinoin etc.).

BRIEF DESCRIPTION OF THE DRAWINGS

The following drawings form part of the present specification and are included to further demonstrate certain aspects of the present invention. The invention may be better understood by reference to one or more of these drawings in combination with the detailed description of specific embodiments presented below.

FIG. 1 Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract, reduce the expression of proinflamattory cytokines IL-8, IL-2, and TNF-α in human epidermal keratinocytes.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Acne is commonly referred to as a disorder of the pilosebaceuous unit, which includes the hair follicle, seabaceous gland, and sebaceous duct. Propionibacterium acnes (“P. acnes”), an anaerobic bacteria, is present in all types of human skin and is part of the skin's natural sebum maintenance system.

Sebaceous glands produce sebum, which is excreted through the sebaceous duct and travels up the follicle. The sebum mixes with common skin bacteria (including P. acnes) and dead skin cells that have been shed from the lining of the follicle. While this process is normal, the presence of extra sebum (note that sebum production can increase when stimulated by hormones such as androgens) can increase the possibility that the pilosebaceuous unit becomes plugged/clogged/obstructed. The end result of this is oftentimes an inflammatory response, which can lead to pimples becoming red, swollen, and painful.

The outward signs of acne on the skin has been categorized as noninflammatory and inflammatory acne. Noninflammatory acne typically includes the presence of whiteheads and blackheads (respectively referred to as closed and open comedones). These comedones are compact masses of keratin, sebum, and bacteria, which dilate the follicular duct. A comedone forms when a follicle or sebaceous duct is plugged/clogged/obstructed. Inflammatory acne has been characterized by papules (pimples), pustules, and nodulocystic lesions which can lead to scarring of the skin.

The compositions of the present invention provide for an effective option for treating, reducing, or preventing acne and its associated symptoms (e.g., presence of open and closed comedones, papules, pustules, nodulocystic lesions, skin redness, etc.) by providing topical skin compositions which include natural botanical extracts such as Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, Hydrolyzed soy protein, Navy bean extract, or Mushroom extract, or any combination thereof. The compositions of the present invention also provide a solution to the above-described problems associated with popular anti-acne agents such as salicylic acid, benzoic acid, benzoyl peroxide, and tretinoin. These types of caustic anti-acne agents can be incorporated into compositions of the present invention at effective amounts while avoiding or substantially reducing the unwanted side-effects. Another advantage is that higher levels of such caustic anti-acne agents can be used, thereby increasing the composition's overall anti-acne effectiveness and the unsightly symptom associated with skin acne.

B. Additional Anti-Acne Ingredients

Additional anti-acne ingredients can also be incorporated in the compositions of the present invention. Non-limiting examples of such additional ingredients include salicylic acid, benzoic acid, benzoyl peroxide, and tretinoin. These forms of anti-acne ingredient when used in effective amounts tend to produce dry, flaky, scaly skin and can also irritate the skin. These adverse symptoms can be reduced or prevented when the ingredients are incorporated into the compositions of the present invention. The symptoms can be reduced or prevented in instances where an effective amount (or excess of an effective amount) of such ingredients are used. This is an added benefit of the compositions of the present invention in that the efficacy of the compositions can be increased by use of such skin-caustic ingredients (e.g., salicylic acid, benzoic acid, benzoyl peroxide, and tretinoin) while preventing or reducing the unwanted side-effects produced by the caustic ingredients.

C. Oxygen Radical Absorbance Capacity

Oxygen Radical Absorption (or Absorbance) Capacity (ORAC) is an assay that measures the antioxidant activity of an ingredient or composition. In essence, it can quantify the degree and length of time it takes to inhibit the action of an oxidizing agent such as oxygen radicals that are known to cause damage cells (e.g., skin cells). The ORAC value of the compositions of the present invention can be determined by methods known to those of ordinary skill in the art (see U.S. Publication Nos. 2004/0109905 and 2005/0163880; Cao et al. (1993)), all of which are incorporated by reference). In summary, the assay described in Cao et al. (1993) measures the ability of antioxidant compounds in test materials to inhibit the decline of B-phycoerythrm (B-PE) fluorescence that is induced by a peroxyl radical generator, AAPH.

Example 3 Reduced Expression of Pro-Inflammatory Cytokines

Problem: The increased bacterial lode within acne lesions draws inflammatory cells into the area stimulated by the increased expression of pro-inflammatory cytokines. As acne lesions emerge, inflammation occurs as the skin attempts to heal itself Overall, redness of the skin surrounding the acne lesion is intensified by the release of pro-inflammatory cytokines.

Solution: In vitro testing was used to examine the effect of plant extracts Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract to reduce the expression of IL-8, IL-2, and TNF-α pro-inflammatory cytokines, which can contribute to a reduction in the intense erythema associated with acne lesions and acne prone skin.

Materials and Methods: Human adult epidermal keratinocytes were cultured at 37° C. and 5.0% CO₂ in standard growth medium. At 70-80% confluent, cells were treated with plant extracts for 5 h in the presence or absence of phorbol myristyl acetate. Following, all media was collected and assayed for inflammatory cytokine production analysis using the FaST Quant Kit—Following blocking, supernatant was added to each array. Each array contains triplicate spots for each cytokine. Arrays were incubated for 3 hours and treated with an antibody cocktail, containing one biotinylated antibody corresponding to each of the arrayed capture antibodies. Arrays were incubated for 1 h and incubated with a streptavidin-Cy5. Arrays were imaged on a Perkin-Elmer ScanArray 4000 confocal fluorescent imaging system. Array images were analyzed using Imaging Research ArrayVision software. Spot intensities were determined by subtracting background signal. Spot replicates were averaged and compared to the appropriate controls. Data was calculated as a percent change from appropriate controls.

Results: A summary of the results is in FIG. 1. These data demonstrate that Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpa extract can act to reduce the expression of known inflammatory cytokines in human epidermal keratinocytes induced by chemical treatment. Together, these data support the ability of these botanical to reduce the potential for skin irritation associated with acne prone skin.

Example 4 Determining Efficacy of the Compositions of the Present Invention

The efficacy of compositions or active ingredients within a given composition of the present inventions can be determined by methods known to those of ordinary skill in the art. The following are non-limiting procedures that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures. The active ingredients (e.g., Arctium lappa (Burdock) root extract, Epilobium angustifolium (Canadian Willowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseira amentacea/Caespitosa Brachycarpa extract, or an anti-acne ingredient (e.g., salicylic acid, benzylic acid, benzoyl peroxide, tretinoin, etc.) or any combination thereof, can be tested for their skin efficacy by using the composition vehicles identified in Tables 1 and 2. As noted in these Tables, the active ingredients and concentration ranges can vary.

Acne treatment can be visually monitored by applying a treatment composition to acne associated symptoms (e.g., open or closed comedones, papules (pimples), pustules, nodulocystic lesions, etc.) and inspecting the symptom over a period of time (e.g., 1, 2, 3, 4, 5, 6, days, 1, 2, 3, 4, weeks, 1, 2, 3, 4, months, etc.). Similarly, Acne prevention can be visually monitored by applying a prevention composition to skin susceptible of exhibiting an acne associated symptom (e.g., chin, cheek, eye, nose, forehead, etc., skin of a child, teenage, young adult, adult, or senior citizen) and inspecting the skin over a period of time. Further, the existence of symptoms associated with acne treatment (e.g., dry, flaky, or scaly skin or irritated skin) can be visually inspected.

Skin moisture/hydration can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72C). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance.

Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether a composition is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a²+b²)^(1/2).

Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.

Clinical grading of skin tone can be performed via a ten point analog numerical scale: (10) even skin of uniform, pinkish brown color. No dark, erythremic, or scaly patches upon examination with a hand held magnifying lens. Microtexture of the skin very uniform upon touch; (7) even skin tone observed without magnification. No scaly areas, but slight discolorations either due to pigmentation or erythema. No discolorations more than 1 cm in diameter; (4) both skin discoloration and uneven texture easily noticeable. Slight scaliness. Skin rough to the touch in some areas; and (1) uneven skin coloration and texture. Numerous areas of scaliness and discoloration, either hypopigmented, erythremic or dark spots. Large areas of uneven color more than 1 cm in diameter. Evaluations were made independently by two clinicians and averaged.

Clinical grading of skin smoothness can be analyzed via a ten point analog numerical scale: (10) smooth, skin is moist and glistening, no resistance upon dragging finger across surface; (7) somewhat smooth, slight resistance; (4) rough, visibly altered, friction upon rubbing; and (1) rough, flaky, uneven surface. Evaluations were made independently by two clinicians and averaged.

Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman et al. (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.

Skin firmness can be measured using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.

Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).

The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and the are of the replicas covered by wrinkles or fine lines was determined.

The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: R_(a)=Standardize roughness; l_(m)=the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height (x-axis).

In other non-limiting aspects, the efficacy of the compositions of the present invention can be evaluated by using a skin analog, such as, for example, MELANODERM™. Melanocytes, one of the cells in the skin analog, stain positively when exposed to L-dihydroxyphenyl alanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM™, can be treated with a variety of bases containing the compositions and whitening agents of the present invention or with the base alone as a control. Alternatively, an untreated sample of the skin analog can be used as a control.
